What is a transition metal?
an element which has an incomplete d-subshell or gives rise to an anion with an incomplete d-subshell
Which group in the d-block are not considered transition metals? Which elements are these?
Group 12 Zn, Cd and Hg
Where are the ligands on a d-orbital?
Along the axes
Which shapes of d-orbitals are influenced more by ligands?
dz² dx²-y²
Which shapes of d-orbitals are less influenced by ligands?
dxy dxz dyz
How would you calculate the number of d electrons?
Group number - oxidation state
What are the d configurations of the 2+ ions in order?
In order of the number of elements Eg. Sc2+ is d1, Ti2+ is d2 V2+ is d3 etc…
How would you then use the 2+ d configurations to work out other ions?
Add or minus electrons according to the charge
What is the d configuration of Cr 3+?
d3
What is the d configuration of Fe 3+?
d5
